ios - 如何在 iOS 9 中创建分享按钮？

Question

在我的应用程序中，我想像这样使用 WhatsApp、Facebook、Twitter、Mail 创建一个共享按钮。

这是我的代码

-(IBAction)share:(id)sender
{
NSString *shareText = @"Hi This is a Reward Game App";
NSArray *itemsToShare = @[shareText];
UIActivityViewController *activityVC = [[UIActivityViewController alloc]initWithActivityItems:itemsToShare applicationActivities:nil];
activityVC.excludedActivityTypes = @[UIActivityTypePostToWeibo,UIActivityTypePostToTwitter,UIActivityTypePostToFacebook,UIActivityTypeMail,UIActivityTypeMessage,UIActivityTypeAssignToContact,UIActivityTypePostToTencentWeibo];
[self presentViewController:activityVC animated:YES completion:nil];
}

我正在写这段代码，我的模拟器显示是这样的，

它只显示邮件和 facebook 图标，我想要像这样的 whatsup 图标消息。

-(IBAction)shareAction:(id)sender
 {    
        NSArray* sharedObjects=[NSArray arrayWithObjects:@"sharecontent",  nil];
        UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:sharedObjects applicationActivities:nil];
        activityViewController.popoverPresentationController.sourceView = self.view;
        [self presentViewController:activityViewController animated:YES completion:nil];
 }
